Herodotus wrote in prose narrative for the very first time while introducing the mythical element and not fully clarifying if an event was true or based on conjecture. His accounts were meant to be read out aloud.
Royal burials in Scythia are confirmed by present day archaeological findings; Xerxess cutting a canal through the Athos peninsula was only recently confirmed by aerial photography. Some of his informants spun him a yarn - the heaps of gold on the Indian plains may be collected using three camels one female camel recently calved held in reserve would escape the giant ants the other male camels would fall to the stalking giant ants. The incredulity that the Phoenicians circum-navigated Africa with the Sun to their right hand, i.e. to the north of them, c. 500 BC is confirmed in Herodotus' account. This happened some 2,000 years before Vasco de Gama, the Portuguese explorer.
Herodotus sets out to preserve the memory of the past by recording the remarkable achievements of the Greeks and other peoples. 'My business is to record what people say, but I am by no means bound to believe it.'
Herodotus was the first Western historian presenting the evidence then informing us of his conclusions, so that if we reject his conclusions we still have the evidence. Hubris is the disturbance of natural order, the reversal of fortune, restoring the natural order is nemesis. Xerxes bridges the Hellespont - a sacrilage because the sea is a God - Xerxes is defeated when the Hellespont bridge is destroyed.
Herodotus emphasise the Greek view that the dramatic reversal of human fortune underlies the Greek respect for moderation.
